摘要: The ternary germanide EuAuGe has been prepared from the elemental components in a tantalum tube at 1070 K. It was investigated by X-ray diffraction on both powder and single crystals. crystal structure determined four-circle diffractometer data: Imm2, a= 460.1(1) pm, b= 737.1(1) c= 788.1(2) V= 0.2673(2) nm3, Z= 4, R= 0.0288 for 1069 F2 values 22 variables. crystallizes new ordered version of CeCu2 type. Its is compared with related TiNiSi-type. Susceptibility measurements show Curie-Weiss behaviour above 40 K µexp= 7.4(1)µB, indicating Eu2+. orders ferromagnetically Tc= 34(1) Electrical conductivity are compatible metallic behaviour.
